I am using NEC v850 architecture freeRTOS porting code with 2MHz oscillator frequency for my project. One of the task is to implement data logger feature. Field data is received at 9600KBaud rate and needs to transmit those data’s to PC application at 38400KBaud rate. Max. received data length is 32 bytes and it may be received approx. every 30ms.
Most of RTOS based application uses higher osc. frequency like 40 to 100MHz. Should i consider higher frequencies for my application? Do you feel 2MHz osc. clock frequency is not at all sufficient to use freeRTOS API?
