stm8s001j3 i/0 control problem
I am having a communication problem with MAX485 ic. I am trying to change Ic receiving mode to transmit mode by using 'PB4' pin and i am using UART1 , SWIM pin as a Transmitter. in some controllers i am unable control pin in the middle working. I am ...
Resolved! STM8S001J3 UART RECEIVING PROBLEM
Hi All,I am using stm8s001j3 controller, PA1 and PA3 are using as a UART communication by using Remapping. i am able to send the data but unable to receive data. UART configuration is GPIO_DeInit(GPIOD);GPIO_Init(GPIOD, GPIO_PIN_6, GPIO_MODE_IN_PU_...
STM8S005K6 SWIM PROG error [42004]: Memory write error
Program memory write stopped working for me. I tried with two STM8S005K6 chips. And everything works fine if I use some other STM8 chip. Getting below error when trying using STVP.Error : Programming failedError : Problem while trying to Reset swim a...
Resolved! Issue with UART1 in STM8S001J3
Hello, I'm having some problems with UART1 in STM8S001J3. I'm using the simple code below (the compilation is ok), but when I try to programming the MCU in STVP, a error happen and the MCU doesn't work anymore, even though I try to programming with a...
I try to disable the SWIM interface in a STM8AL3168 derivative but it does not seem to work (see details). What am I doing or thinking wrong?
I try to disable the SWIM interface in a STM8AL3168 derivative, by setting the SWD bit of the global configuration register (CFG_GCR) = 1 in main().typedef struct CFG_struct{ __IO uint8_t GCR; /*!< Global Configuration register */}CFG_TypeDef;#define...
Resolved! Reading STM8 registers with STVD in debug mode?
WIth the STVD software in Debug mode and connected to the STM8 MCU via the ST-LINK/V2, is there a STVD feature that displays register content? Thank you!
