After the STM8L152K6 device is programmed by swim, it must be turned off and then on again for normal operation
After the STM8L152K6 device is programmed, it must be turned off and then on again for normal operation. However, if the STM8L152K6 device resets by pressing the Reset button after programming, it does not work. I have to do the power on reset once ...
How do I install the firmware library?
I am (obviously) brand new to stm tools. I have installed the stvd and cosmic compiler and I want to use the firmware library. I have downloaded the STMS version. How do I install and use it? I've googled til my fingers are sore.
STM8L051 125khz PWM not work
I have new application used stm8l051, The MCU using timer2(GPIOB2) to generator 125khz PWM, duty cycle from 0% to 100% every 500ms with 16Mhz clock source.void Timer2_PWM_Init(void){ GPIO_Init(GPIOB, GPIO_Pin_2, GPIO_Mode_Out_PP_High_Fast); CLK_Peri...
I have downloaded Cosmic C compiler software for STM8. But unable to receive the key
I have sent request to send the key for STM8 Cosmic C compiler arround 3-4 days back but unable to receive till today. Can you send the license key
Can I store a 4 Bytes of const object into end of flash memory region (for example address 0x17f80).
Based on Cosmic compiler document, I am trying to use #pragma to store the const object into flash memory region 0x17f80. Even I have configured the liker config,Then I have added below code in .c file.#pragma section const {applflag}const u32 appl_f...
STM8L : why is the beginning of flash memory (0x8000 to 0x9200) erased/modified after power off ?(!)
Hello,When I flash a user application to STM8L with STVD, it works fine. As long as I do NOT power off MCU, I can read back flash content with STVP. For the first byte located at address 0x8000 (beginning of IT vector table), value is 0x82, which is ...
Save initial EEPROM data when burning MCU
When initially burning the MCU, I want to save some EEPROM data. Lets say the data 123 is to be saved in location 1 of EEPROM. If I write the below C code before the main function, will it work? Once the data is stored the first time the program is b...
Not getting interrupt of Timer2 input capture in STM8S003F3 .
Hi,I am using input capture of Timer2 Ch1 in stm8s003f3(20 pin uC). I had configured the timer 2 and provided pulses in PD4 pin , but i am not getting interrupt in Timer2 interrupt handler.void InitTimer2(void){TIM2_DeInit();CLK->PCKENR1 |= 0x20; ...
Inverse of dead band observed in PWM, STM8S003F3
1. I have written below code for PWM generation for STM8S003F3. Two pwm pins are used inverted with dead time.2. But I observed this graph on CRO of two pins is this. I was expecting one pin to turn off before another turn on i.e deabband.. But rever...
