Resolved! How to configure PC0 and PC1 as ordinary pins on STM8L051F3?
Hello! I am using STM8L051F3 with Stm8 SPL headers. I am trying to configure PC0,PC1,PC4 as output with high level:CLK->PCKENR1 &= `CLK_PCKENR1_I2C1; GPIOC->DDR |= (1<<0)|(1<<1)|(1<<4); GPIOC->CR1 |= (1<<0)|(1<<1)|(1<<4); GPIOC->ODR |= (1<<0)|(1<<1)...
How to declare RAM variable as volatile in STM8 assembly language
Hi All,I want to know how i can declare any RAM variable as volatile in STM8 assembly language. I have one variable, which is shared between ISR and main function. It is causing issue during updates, when the software is in free run mode.Can anyone t...
Regarding POR.The input voltage drops to higher than 0V, and then rises again. Can STM8 work normally in this case?
The input voltage drops to between 0V and VIT- （Brown-out reset threshold） , such as 2V，and then rises higher than VIT+ （Power-on reset threshold）again. Can STM8 work normally in this case?

STVP v3.4.1. CONFIGURATION:Hardware: STLINK-V3SETProgramming mode: SWIMDevice name: STM8L051x3Port: USBJP4 and JP6 (SWIM ON) jumpers are installed. All 4 pins of CN4 are connected to the target. The target is the bare chip on a dip adapter, plugged i...
Need to write and read reliably to a protected block of EEPROM memory from startup to startup
Hi. I'm using an STM8 MCU. I'd like to reliably write to and read from a block of EEPROM/FLASH memory (about 1k) that will never be overwritten either by the MCU or by programming/debugging via SWIM, but can be read and written from code. I'm writ...
Problem CAN_ReceiveAll in standard peripheral library
I develop stm8 using cosmic compiler and v.2.3.1 standard libary.I think there is a problem with the definition of CAN_ReceiveAll.In this function I can get an address of _Data variable.But, I can not get the address in Caller side.My thoughts should...
