Hi,
On our custom board we are trying to generate Clock on MCBSP with 2700bps data rate. But we were unable to do it after gone through details of the clock source for MCBSP.
Can we generate the clock for that data rate (2.7KHz) with MCBSP?
Now we are generating clock on GPIO pins based on the timer tick.I'm attaching the source file.
timer_test.c is the code for toggling gpio for 2700KHz
timer_app.c is the user space application to enable timer.
we are facing problem with clock jitter. it is varying between 2695KHZ and 2710KHZ. We are looking for exact 2700KHZ on our application.
My clock tree is
SystemClock = 19.2 MHz
DPLL_MULT_VALUE = 242
DPLL_DIV_VALUE = 13
CORE_DPLL_CLK = 663.771 MHz
CORE_CLK = 331.8855 MHz
L3_CLK = 165.9427 MHz
Can we achieve 2700KHZ with MCBSP??
Thank You
