RTC drifting - a lot!

I have bought a STL8L Discovery kit and have installed the example for showing a clock: RTC using LSE - but it drift appx. 5 seconds per minute.Seems like a simple 555 timer - or a cheap old analog clock - is more precise.

Which Pin is triggering an interrupt How do I count them not multiple time?

Hello everybody,how can I count which pin triggers an interrupt, but not multiple times? I have written the following ISR. INTERRUPT_HANDLER(EXTI_PORTB_IRQHandler, 4) { data = (uint8_t)GPIOB->IDR& 0xF; if((GPIO_PIN_0 & data )== GPIO_PIN_0) { co...

is it possible to flash stm8s using stm32f0discovery?

Reading 0x00 in SPI_DR of SPI Communication

Sir,I am working on STM8S003F3P Controller which is interacting with LoRa SX1276 HPD Module. I have the experience of working on SPI and have enough knowledge to configure it. I am able to write the data to SX1276 (I will tell you how). But, while R...

STEVAL-ISA164v1 not correctly responding

I've got a new STEVAL-ISA164V1 Board.The problem looks like this:When connecting with the ST SMED Configurator there is a warning:The chip on my board is double checked a STNRG388A (well that's what is printed on the chip)I can connect and it looks l...

I want to power a receiver (ISB68RX and ISB68WA) with ISB047V1T, but ISB047V1T keeps reseting after 5 seconds. It resets when it is powered via usbc, but when connected via micro-usb it stops blinking the leds and it is not recognized by STWBC GUI.

Fix I2C ACK delay

How can I fix the super long delay and weird ACK glitch with I2C on STM8S?I'm having some troubles with I2C communications between a raspberry pi and STM8S. The STM8S is a slave transmitter and I2C is running at 100 KHz. It works much the time, but I...
