Discuss STM8 microcontrollers, including SWIM, USART configurations, RTC usage, ADC issues, and debugging.
Hi everyone, I'm using the STM8L152R8 Nucleo board and trying to get the RTC running on the LSE clock. It works but only inconsistenly, about 2/3 runs error out in the RTC_EnterInitMode function of the SPL the below line. RTC_EnterInitMode is called ...
Hi :) Quick version: how to write 2 bytes (not in the same word) to the EEPROM in STM8? Should I write 1 byte and then wait for the EOP flag to be set before writing the second one?Long version: for now I am simply doing:unlock EEPROMwrite byte 1 (EE...
in my testing while I am down the power or power on of a any channel MCU is going to reset . I have attached a schematic of my board.If is there may issue of softwere code please suggest me the clock setup is void clock_setup(void){ CLK_DeInit(); ...
Hi everyone, I'm writing a program for a STM8L152R8 that sends data over UART to another mcu that should respond to me though I have a timeout on the transaction of five seconds using timer 4. I'd also like to include a watchdog however the max timeo...
Hi!There is an issue with unlocking the EEPROM on STM8 (probably all of them, but I am using STM8L151). This article summarizes the issue very well: https://slime.systems/content/stm8-eeprom-bug/There it says it was first found in 2013, and here we a...
Hello,I am trying to understand if TIM2 can still work for PWM output in low power modes. I can't find which peripherals are allowed to be on in the STM8L151F2 datasheet for the low power modes.To expand on my question. I assume that in Wait mode I ...
I am using STVD - IDE for STM8L and STM8A series. We want to do static code analysis for the code. Kindly suggest me tool which can be integrated with STVD or any other IDE -STM8 support static code analysis.
Hello allCan anybody help me to understand the CCRL register?I´m using a 20 kHz crystal, so in the register I2C->FREQR i will put the value of 20, is it right?And how about the CCRL register, what is the correct value for the standart mode?I fount t...
I've encountered a strange progressive bug on ST Visual Develop where the IDE gets progressively wonky as I run the debug to program my STM8S001J boards. First the icons start to look shifted and weird, then windows start disappearing and reappearing...
To check halt mode i've set all gpio's to out mode, but some of them was on same line with SWIM. Now i can't promgram mk =) How can i solve this problem? Maybe there is any way to hard clean memory? STM8L050J3M3SOLVEDDatasheet page 23 (https://www.st...
