Not able to generate 6 step pwm signal using timer1
Hi,I am working with stm8s105c6 controller. I want to generate 6 PWM using timer1. For that I am using 6 step PWM sample. I am getting pwm at pc1, pc2, pc3 but complementry pwm at pb0, pb1, and pb2 is not available.At pb0, pb1 and pb2 I am constantly...
STM8S SWIM pin unused handling
Hello everyone.I am in trouble with the SWIM pin of STM8S.According to the data sheet, unused pins should be set to OUTPUT.However, I would like to keep SWIM pins in a state where they are normally unused and can be debugged only when necessary.How c...
Resolved! Which STM32 flasher to use for STM8
Hi all, I'm working on a part that has implemented something very similar to the ST-provided user bootloader for the STM8. I've tired uploading a binary using several versions of the STM flasher but none of them seem to work. Is there a script availa...
Are the UART pins of the stm8s103 5v tolerant?
Hello, I have looked in the datasheet and there is no "FT" like the stm32 family has. It does show that the UART pins are "HS" (high sink current). Can I assume there is something like a zener diode plus resistor to protect the core from 5 volts? Tha...
Resolved! ST-Link / V2 to program STM8S001J3 with STVP but not connect with the device
Hello, I'm using ST-Link / V2 to program STM8S001J3 with STVP (Swim connection). When I try to program MCU, the error appears that it was not possible to connect with the device. The pins are correct and I'm using 3.3V (Pin 19 to CN3 of ST-Link).Even...
