CH552 windows 开发工具

# CH554 software development kit for SDCC [](https://travis-ci.org/Blinkinlabs/ch554_sdcc)  This is a port of the CH554 SDK, from Keil C51 to SDCC. The CH554 family of microcontrollers is notable because it has both an extremely low cost, USB device and host peripherals, and a preloaded USB bootloader. # Getting Started ## Get the toolchain: Windows You'll need a recent version of SDCC, as well as mingw for make, and likely also git-bash for the bash shell. Additionally, you'll need WCHISPTOOL to upload code to the chips. * [git for windows](https://github.com/git-for-windows/git/releases/download/v2.15.1.windows.2/Git-2.15.1.2-64-bit.exe) * [SDCC 3.6.0](https://sourceforge.net/projects/sdcc/files/latest/download?source=files) * [mingw installer](https://downloads.sourceforge.net/project/mingw/Installer/mingw-get-setup.exe) * [WCHISPTOOL](http://wch.cn/download/WCHISPTool_Setup_exe.html) TODO: How to set up the enviroment to find these bits automatically Once the tools are installed, add the following lines to the end of your .bashrc file: # SDCC compiler tools export PATH=$PATH:/c/Program\ Files/SDCC/bin # Mingw tools (for Make) export PATH=$PATH:/c/Qt/Qt5.10.0/Tools/mingw530_32/bin alias make=mingw32-make.exe TODO: Use standalone mingw tools instead of the ones from Qt ## Get the toolchain: Linux For Debian-based systems, this should work: sudo apt-install build-essential sdcc We got a open-source implementation of this ISP Tool. You will get it from the following link: * [LibreCH551](https://github.com/rgwan/librech551) It works fine on CH551 and CH554. The Makefile has "flash" operation, you have a convenient way to flash your chip. This program and operation also works on Windows (need Zadig to install driver) and Mac OS. The usb-device-cdc-i2c example show you how to have a in-application firmware upgrade, it will make use of prelude flash operation.. ## Get the toolchain: macOs You'll need xcode (for make), as well as SDCC. ISP Tool will be same as Linux's. ## Build the examples Then clone this repository, and build the examples: git clone https://github.com/Blinkinlabs/ch554_sdcc.git cd ch554_sdcc/examples make If everything is set up correctly, all of the examples should now be built. Use the 'WCHISPTool' to flash an image onto the target device. ## Port a file from Keil C51 syntax to SDCC The syntax for the two compilers are slightly incompatible. Notable issues from the SDK are: * SFR and SBIT defines are different * Absolute addressing format is different * SDCC doesn't automatically track absolute-addressed variables * SDCC can use standard types like 'uint8_t', the C51 examples used non-standard defines like 'UINT8' * SDCC is little endian, while C51 appears to be big endian This project includes a simplistic python script that can automatically translate some simple grammer changes. It can be used like this: python tools/c51_to_sdcc.py [source] [destination] With any luck it should do 90% of the translation work for you. ## Create a new example Create a new directory in the examples folder, with the name of the new example: cd examples/ mkdir fastblink cd fastblink Add a Makefile that referes to the master template makefile: vi Makefile With these contents: TARGET = fastblink C_FILES = \ main.c include ../Makefile.include Change the definition of target to match the new example name. Next, add a barebones main file: vi main.c With these contents: // Blink an LED connected to pin 1.7 #include <ch554.h> #include <debug.h> #define LED_PIN 7 SBIT(LED, 0x90, LED_PIN); void main() { // Configure pin 1.6 as GPIO output P1_DIR_PU &= 0x0C; P1_MOD_OC = P1_MOD_OC & ~(1<<LED_PIN); P1_DIR_PU = P1_DIR_PU | (1<<LED_PIN); while (1) { mDelaymS(10); LED = !LED; } } And compile: make Oops! There is a problem: $ make sdcc -c -V -mmcs51 --model-small --xram-size 0x0400 --xram-loc 0x0000 --code-size 0x37FF -I../../include -DFREQ_SYS=12000000 main.c + /usr/bin/sdcpp -nostdinc -Wall -I../../include -DFREQ_SYS=12000000 -obj-ext=.rel -D__SDCC_MODEL_SMALL -D__SDCC_FLOAT_REENT -D__SDCC=3_5_0 -DSDCC=350 -D__SDCC_REVISION=9253 -D__SDCC_mcs51 -D__STDC_NO_COMPLEX__ -D__STDC_NO_THREADS__ -D__STDC_NO_ATOMICS__ -D__STDC_NO_VLA__ -isystem /usr/bin/../share/sdcc/include/mcs51 -isystem /usr/share/sdcc/include/mcs51 -isystem /usr/bin/../share/sdcc/include -isystem /usr/share/sdcc/include main.c + /usr/bin/sdas8051 -plosgffw main.rel main.asm sdcc main.rel -V -mmcs51 --model-small --xram-size 0x0400 --xram-loc 0x0000 --code-size 0x37FF -I../../include -DFREQ_SYS=12000000 -o blink.ihx + /usr/bin/sdld -nf blink.lk ?ASlink-Warning-Undefined Global '_CfgFsys' referenced by module 'main' ?ASlink-Warning-Undefined Global '_mDelaymS' referenced by module 'main' + /usr/bin/sdld -nf blink.lk returned errorcode 512 ../Makefile.include:38: recipe for target 'blink.ihx' failed make: *** [blink.ihx] Error 1 Right, we forgot to add the debug.c source file to the Makefile. Update the Makefile so that it looks like this: TARGET = fastblink C_FILES = \ main.c \ ../../include/debug.c include ../Makefile.include And re-run make.

The .hex file can now be loaded onto the target using WCHISPTOOL. ## Build configuration variables The build configuration is specified in the master Makefile.include file, however some variables can be overridden by the local Makefile: | Makefile variable | Description | | --- | --- | | TARGET | Example name, used to name the .hex file | | C_FILES | List of c files to include in the example build | | FREQ_SYS | System clock frequency. Default is 12000000 (12MHz). See 'include/debug.c' for a list of accepted values | | XRAM_SIZE | Size of the non-reserved XRAM. Update to reserve a portion of the XRAM for absolute variables, such as for the USB DMA pointer | | XRAM_LOC | Starting position of the non-reserved XRAM. Update to reserve a portion of the XRAM for absolute variables, such as for the USB DMA pointer | | STDIO_UART | Set to '0' to use UART0 for STDIO, or '1' to use UART1 for STDIO (not finished) | # Status Here is a list of the different peripheral drivers and examples that need to be ported | Peripheral | Description | Status | | --- | --- | --- | | ADC | Analog-to-digital converter | not started | | DataFlash | DataFlash (EEPROM) peripheral | not started | | GPIO | I/O peripheral example | not started | | UART0/stdlib | stdio example using UART0 | in progress | | UART1/stdlib | stdio example using UART1 | in progress | | Watchdog | Watchdog timer configuration | not started | | IAP | Jump from user program to the bootloader | complete | | PWM | Pulse Width modulation peripheral | com
