Propper use of RSF bit.
According to the datasheet the RTC_ISR1_RSF bit is by hardware when the shadow regs are updated. Is it safe to assume that the shadow regs will not be updated when the RSF bit is already set?

SPI Communication with external device on STM8AF Discovery Board
Hello, I am using a STM8AF discovery board for prototyping and coding development. I would like to use it to establish SPI communication with an external ADC, the ADS1118 from TI. On the datasheet for STM8AF, "The microcontrollers of the STM8AF and S...
hook up stm8s-discovery SWIM programmer and MCU with independent power supply
I have a board with a STM8S0003F3P6 MCU with its own 5V supply and a few other power supplies. What is the safest way to connect STM8S discovery SWIM programmer?protect 5VThe SWIM pin 1 USB 5V and board 5V could be at different voltage levels. I don...
STM8L051F3 How should external interrupts be cleared?
Hello,There is confusion regarding the EXTI_SRx bytes.After a power on reset if a gpio (D0) is configured as input with interrupt and interrupts are enabled,What is the state of the EXTI_SR1 and EXTI_SR2 bytes when the interrupt handler runs?Do both ...
Resolved! removing illegal and critical bytes from your code
I want to know how to view the critical bytes of a .list file. Which byte above the location is critical bytes, is the one to be removed
SPI reading issues
i have configured the spi in stm8l controller.I have attached the code below:void SetupSPI(){ PB_DDR |= BIT(6) | BIT(5) ; // mosi and sck as output. PB_DDR &= ~BIT(7); // miso as input. PB_CR1 |= BIT(7); PB_CR1 |= BIT(6)| BIT(5) ; // mosi and **** a...
stvp Batch programming
After stvp loads the stm8s programming code and option byte, the created project file is copied to another computer in the workshop. After the directory file is changed, the .stp file cannot be opened. The reason is that the stvp adds the burning cod...
Why errors are being shown when i add header files and c files in my code?
Hai, i have written a code for stm8l using st visual and i have added few header files for my code.When i add the files i am getting the error as shown in the image.the following are the header files added:stm8l15x_spi.hstm8l15x_SPI.Cstm8l15x.hPlease...
Option Byte Programming - Critical
Hi,I am trying to program the option byte in STM8S003 controller. I am able to do the same using STVP tool. It is not a practical method on production, so want to add the option byte config in the source code. for that I added the below code snippet....
