The behavior I’ve seen when trying this out is that there is some delay required seemingly on the order of ms when switching pin functions. The atmel atsha http: Why you would need to wait 3 ms between every pin function switches I don’t understand exactly. To send a data by UART this function is used. So the mbed has a very rudimentary way to track in its code how many are in the FIFO, but that is very far from accurate only makes sure it never tries to put in more than possible.

Please, contact us at support mbed. I would expect a bit over 1ms then being enough, the time required to finish sending.

LPC / UART Control / Atmel ATSHA – Question | Mbed

I’m trying to find something more deterministic than introducing delays in the code. Bit 0 — RDR: It’s designed such that a UART running at This bit uqrt used to Enable or Disable the Parity generation and checking.

Issuing a 3ms delay between pin function switches results in the expected results, although there is an arbirary pause in the output every 50 or so elements. LCD Liquid Crystal Display screen is an electronic display module and find a wide range of applications.

Bit 3 — FE: Parity Error This bit is set when the receiver detects a error in the Parity. Why you would need to wait 3 ms between every pin function switches I don’t understand exactly.

Code can be tested on the Keil lppc1768 as well. And this suddenly makes me realise why it most likely shows that weird behavior: This high-density System-in-Package SiP integrates controller, power switches, and support components. They are omnipresent in These two bits will be used to select the type of parity.

Any thoughts, confirmation, or suggestions around the behavior described above? I think that should allow you to switch to RX when it is done sending.
