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...
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...
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...
Need help: can't get my stm8 I2C slave code to interrupt
I am writing from an esp32 I2C master to a stm8s103f mcu. My scope shows the esp is sending a clean read addr byte onto the scl/sda pins (PB4/PB5). But the stm8 is not running my interrupt routine. I have a gpio pin that should toggle when the interr...
Using external editor (like vscode) with stvd?
I've been using vscode as my editor since the one in stvd seems to have features from 15 years ago. I have files also open in stvd since clicking on errors opens files. This means that when I switch to stvd from vscode I get the warning about files...
