ATM8AF: activate Ports for GPIO usage
Hello Community,I'm struggeling with the GPIO activation of Pin PB0.My Setup is: µC: STM8AF6213PCA with TSSOP20 Pinout, STVD + Cosmic C CompilerIt is no problem to aktivate the Port C (PC4, PC5, PC6 and PC7). But port B seems to be dead.But the port ...
How to configure correctly the STM8S005C6 clock to use the HSI oscilator at 16Mhz?
Using the library functions the micro freezes and enters a CLK assert, this is the code I use to configure the CLK: CLK_DeInit (); CLK_HSECmd (DISABLE); CLK_LSICmd (DISABLE); CLK_HSICmd (ENABLE); while (! CLK_GetFlagStatus (CLK_FLAG_HSIRDY)); CLK_Clo...
CANBus, Ethrnet and RS232 on the same MCU
Hello for a project I will be using Ethernet, CANBus and RS232. Now the maximum frequency for CANBUS is 1 Mbit per seconds, for RS-232 that is 20 k baud and for Ethernet I think it is again 1 Mbit per seconds. So with a MCU that has at least 2 MHz c...
Does stm8l001j3 support Flash Loader Demonstrator tool
hello,I want to use Flash Loader Demonstrator for complete programmed update of stm8l001j3 device.But Flash Loader Demonstrator tool unrecongnized device.Is there any other way to update the program through the serial port ?
How to implement micros() function on stm8s003?
I need to decode ASK/OOK signal, for this aim I need to know the period in microseconds between several edges. I decided to use TIM1 for this purpose, here is my code// Set fCPU = 16MHz CLK_CKDIVR = 0; CLK_PCKENR1 = 0xFF; CLK_PCKENR2 = 0;...
Is there a way for the STM8L DAC to retain its output voltage without drawing 80 uA during Halt mode?
I'm using Comparator 2 on the STM8L151G4 with DAC1 on the inverting input. When the DAC outputs 0V, the current draw during Halt mode is < 1 uA. If the DAC outputs around 0.5V before the program enters Halt mode, the current draw is 80 uA in Halt mo...
UART issue for reading 2 or more bytes length
I am having an issue with the UART1 communication between two devices (Computer and a STM8S208 board).I implemented software in the computer that writes two bytes length of data to the STM8• the first byte that acts as an identifier;•the second byte ...
