Open-Sources device headers for all STM8 microcontroller series, namely STM8A, STM8S, STM8L, STM8AF and STM8AL.
Device headers
- are compatible with SDCC, Cosmic and IAR.
- can be mixed with the respective STM8 Standard Peripheral Library (SPL) by STM (see below example). Note that SPL must be patched for use with SDCC, see e.g. here.
Headers were generated from device descriptions in XML format, which are in folder XML. These descriptions could be used e.g. for a graphical debugger interface.
The below projects have been ported to use these open-sources device headers for STMo.
atomthreads
- port is available under https://github.com/gicking/atomthreads, see "ports/stm8_oss"
- all provided tests have passed for SDCC, Cosmic and IAR. Exception is IAR/queue9 which exceeds the size limit of my demo license
These projects have been tested successfully with SDCC, Cosmic and IAR.
adc_measure
- measure analog voltage every ~500ms
- print value via UART using printf()
blink_interrupt
- blink LED in TIM4 interrupt service routine
blink_noInterrupt
- blink LED with a simple NOP() loop
calculate_CRC
- periodically calculate CRC over pre-defined data
- measure time for CRC calculation
- print time and calculated CRC to UART
- CRC32 code copied from https://github.com/basilhussain/stm8-crc
- SDCC uses optimized assembler, IAR and Cosmic C implementation
I2C_LCD
- Periodically print text to 2x16 char LCD attached to I2C
- LCD type Batron BTHQ21605V-COG-FSRE-I2C 2X16 (Farnell 1220409)
low-power_auto-wake
- enter power-down mode with wake via port-ISR or AWU
millis_delay
- implement 1ms ISR, millis(), micros() etc., similar to Arduino
pin_interrupt
- TLI interrupt on pin D7 (not port). Corresponds to INTx on Arduino
pin_read_write
- read and write pin states without interrupts
port_interrupt
- port interrupt on pin PE5. Corresponds to port change interrupts on Arduino
PWM_generate
- generate a PWM on pin PD2/TIM3_CH1 (=pin 3 on sduino)
read_unique_ID
- read unique identifier and print via UART
- Note: UID not supported by all devices
read_unique_ID
- read unique identifier and print via UART
- Note: UID not supported by all devices
read_write_D-flash
- save data to D-flash/EEPROM and read back
read_write_option_bytes
- change option bytes, e.g. activate/deactivate the ROM-bootloader
read_write_P-flash
- save data to P-flash and read back
serial_gets_printf
- serial input/output with gets and printf
- without interrupts or FIFO
serial_printf
- serial output via printf
- without interrupts or FIFO
serial_printf_FIFO_interrupt
- serial output via printf
- using Tx & Rx FIFO and interrupts
- similar to Arduino Serial class
serial_write
- echo read bytes from UART
- without interrupts or FIFO
Single-Wire_DS18B20
- adapted from https://github.com/jukkas/stm8-sdcc-examples
- read temperature from DS18B20 sensor using 1-wire
- display readying to 8 digit 7-segment LED display with MAX7219 controller
SPI_LED_MAX7219
- adapted from https://github.com/jukkas/stm8-sdcc-examples
- SPI output to 8 digit 7-segment LED display with MAX7219 controller chip
- count up every 1s
STM8_StdPeriphLib
- mix with functions/headers of the STM8S Standard Peripheral Library (SPL)
- SDCC compatibility requires patch, see e.g. here.
