ChibiOS Free Embedded RTOS

Hello,

I want to send and receive hex bytes over Serial. I guess chIOPut sends uint8_t. Can anyone help me with this? Is there any way other than chIOPut and chIOGet to send and receive data in hex bytes?
I am using STM32F4 discovery board with ChibiOS 2.4.3

I assume that for "hex bytes" you mean sending bytes as two ASCII characters, you can use chprintf() for that. Remember it is just ASCII data, handle it as such.

I dont want to deal with data in ascii. I want to send and receive data as single hex byte. for example I want to send only 0xC1 and receive 0xC1 as a hex byte.

Bytes are bytes, there are not decimal bytes or hexadecimal bytes. Any function exchanging uin8_t data exchanges bytes.
