if i normolly send is "cake 50 %" to arduino receive "cake 50 %" after 10 times arduino receive "cake 50 BBBB" then all receive all "BBBC" but the usart1 vcp is sending normally this is a way to solve it?

If i configure D1 pj8 as tx for uart8，D0 pj9 as rx for uart8.When i conect to led directly D0（rx） could let led on but D1（txno in this case should be right ？Both pin with GPIO_MODE_AF_PP//PULLUPstatic void MX_GPIO_Init(void) { GPIO_InitTypeDef GPIO_...

MB1248-D03After HAL_GPIO_Init(GPIOJ, &GPIO_InitStruct); I think should not add HAL_GPIO_WritePin(GPIOJ，GPIO_PIN_8，1) ？In my debug gpioj run asIn my register D0/D1 as（i dont know its same thing o no）which part of rcc should i check uart 8

if i reply some question noone answer my reply，and i wait a few hours no one reply，but those Evangelists never answer a other day， for this reason i created ，if it not right I‘m sorry.

" how the code is called" not this HAL_UART_Transmit(&huart8,(uint8_t*)msg,strlen(msg),100)? en usart1 (same configution but with no pin use usb)is "beer 50 % cake 50 % etc" run as 0V."high/low in a manner you can review / inspect" this mean writepi...
