Re: RMT interrupts

Wow, actually it succeeded as follow..With the following interrupt routine I was able to get data for channel 0: void IRAM_ATTR rmt_isr_handler(void* arg){ //read RMT interrupt status. uint32_t intr_st = RMT.int_st.val; RMT.conf_ch[0].conf1.rx_en = 0; RMT.conf_ch[0].conf1.mem_owner = RMT_MEM_OWNER_T...

Re: RMT interrupts

Thanks for letting me know....Seems like I'm on the correct way. But why no data? I will next try to unset the enable bit and ownership. Looking forward what happens.....Thx again

Re: RMT interrupts

I'm still investigating to get my own RMT interrupt running. At the moment I'm worrying, if rx_en is really enabled with my code above and if I'm really accessing to the correct memory address (RMT_MEM_PD)?? Would be happy to find someone who has some experience with it... Thx

Re: RMT interrupts

Hmm, yes, that makes sense. I assume that in this case you will use rmt_set_rx_intr_en( config.channel,true); rmt_isr_register(rmt_isr_handler, NULL, ESP_INTR_FLAG_LEVEL1, &xHandler); Instead of: rmt_driver_install(config.channel, 100, 0)): By this I managed to hook the interrupt and disable the rin...

Re: RMT Receive ISR handler

Whats about calling it like this? rmt_isr_handle_t xHandler = NULL; void IRAM_ATTR rmt_isr_handler(void* arg){ ... } rmt_config_t config; config.rmt_mode = RMT_MODE_RX; config.channel = (rmt_channel_t) _channel; config.gpio_num = (gpio_num_t)pin; config.mem_block_num = 1; //how many memory blocks 64...

RMT - simplest receive example with Custom Interrupt

Im trying to implement an RMT Receiver at RMT channel 0 with my own interrupt. The interrupt is already fired successfully, but inside the interrupt, I can not get the correct data. This is how my interrupt is coded: rmt_isr_handle_t xHandler = NULL; void IRAM_ATTR rmt_isr_handler(void* arg){ //read...
