I am trying to get a pulse out of TIM2 in compare mode but I see no output. Here is my snippet of code:#include "iostm8l101f3.h" void main( void ) { CLK_CKDIVR = 0x01; // 8MHz PA_CR1 = 0xFF; // all pullups PB_DDR = 0x01; // 0000 0001...
Hello,I am developing a project with STM8L050J3 microcontroller using Evaluation Board STM8-S08-DISCO and STVD version 4.3.12.I need to calibrate the internal HSI oscillator, but for some reason that I have not been able to identify, although I compi...
I have this little project for the STM8L101F3 that just writes an arbitrary value to TIM2_CCR1H and TIM2_CCR1L and then tries to start the timer but I get nothing from the timer output.If I run the project with a debugger and inspect the contents of ...
$ sdcc -mstm8 --out-fmt-elf -o build/firmware.elf build/{main.rel,uart3.rel,misc.rel}?ASlink-Warning-Undefined Global 'null' referenced by module 'main'What is meaning?Module "main.rel" was compile without errors/warning.stm8-gdb has segfault when i ...
Hello, there is posibility we mixed STM8L101F3 vs F3U. There is marking L1S3 on the top, but I can't find any information/table of these markings. Is is possible to have it ?
Hello, I am using the Stm8s003f3p6 processor. I want to create 1 microsecond time on processor. I tried TIM1 and TIM4 peripherals for this. I gave the values of 2, 4 and 8 respectively as Presecaler values. Again, I gave 7, 3 and 1 values as periods,...
The right side of the source code displayed in ST Visual Develop is displayed in red.Does anyone know how to solve this?Also, is there any problem if it is displayed in red?I would appreciate it if anyone could tell me.
1. What happens if TIM2_ARR is 0xFFFF? Does overflow occur when timer counter counts past 0xFFFF?2. What happens to compare output after TIM2 overflows? For example, lets say that the TIM2_CCR1 = 0x7FFF so the output changes state when the counter co...
We are interfacing HSD to drive DC-Motor with STM8-MCU.We are expecting current sensing output at the Multi-sense pin of HSD.Selection of Channel is as per datasheet of VND7140AJTR.But, when Motor is ON, and Channel-0 is selected for CURRENT sense, w...
