There is nothing about sending serial data that needs to happen IMMEDIATELY, when sending serial data is sssllloooSo, what is it, EXACTLY, that you are trying to accomplish? Do not repeat the lame "check how to use arduino mega for interrupt based serial communication" statement, since sending and receiving serial data is already interrupt based. Interrupts are meant for things that must be dealt with immediately, like serial data arriving, the clock ticking, etc. we can t log you in because of an issue with single signon contact your salesforce admin for help toy convention 2022 does united healthcare cover anesthesia for. While interrupts are disabled you use two functions that rely on interrupts, so that code is never going to work. so following code sequence can be followed without having any delay. See the corresponding section of tutorial: Getting started with MicroPython on the RP2xxx. Unlike, a polling method, a UART interrupt method doesn’t wait for the data and keep executing or doing other tasks. Hence, I was wondering if there are any ways to implement UART interrupt with Python so that whenever there is incoming data, I will do an arduino. So once there is some data is rcv buffer then only read the data using read function. Of course, you only do it at the end, when they would be re-enabled anyway, so doing it is pointless. Instead of using time.sleep (), its preferred to use serialport.inwaiting which help to check the number of bytes available in rcv buffer. This value is by default set to 5 and if the DMA and UART interrupt have the. That seems to exclude you, so you should not be enabling interrupts in the ISR. This example project is based on a PSoC Creator starter design for the. Where it is done, the person writing the code has a COMPLETE understanding of interrupt handling, interrupt priorities, and of the possible problems that will arise. Re-enabling interrupts in an ISR is not something that is typically done. In an ISR, interrupts are already disable, so the noInterrupts() call is useless.
