Just use a timer interrupt That's what I ended up on doing, Only issue is I need three of these triggering at different times (with an interrupt triggering the respective timer and switching the others off) Although this code works perfectly to start the timer: gpio_set_level(32, 0); gpio_output_di...

Hi WiFive, This was the other option I was thinking of doing. I was hoping that maybe the ledc module could do this. I'd say if the timer has a period of 20 mins with a 10% duty, then a variation of 5% or less would be preferred. I'm not too familiar with the esp32's timers. How would I go about set...

Hey everyone, I'm starting to dig around and have been fooling with the ledc module, but I don't think it will fulfill my requirements completely. I need to generate a very slow pwm signal, somewhere in the order of having a period of 10 to 20 minutes. The duty will be fixed Is there anyone I can ge...

Hey everyone, In my code upon wake up I want to have the esp retrieve time using sntp. The sync works perfectly the first time as it updates from 1970 to 2019, althought I have no idea what to make the condition for subsequent sync's to allow it to resync. time_t now = 0; struct tm timeinfo = { 0 };...

HI Ritesh Prajapati, Sorry I completely forgot to reply and have still not gotten this working.

Hey everyone, I've got my SPI init code defined as the following: #define GPIO_MOSI 21 #define GPIO_MISO 14 #define GPIO_SCLK 12 #define GPIO_CS 22 ESP_LOGI(TAG1,"Started master SPI"); esp_err_t ret; spi_device_handle_t handle; //Configuration for the SPI bus spi_bus_config_t buscfg={ .mosi_io_num=...

hey everyone, For some reason the coredump utility is providing me with nearly no info. It either just says that a brownout procured or that it couldn't access some memory region or some other random info. I had a look at kolbans book and in it he gets the exact line at which the error occured. I c...

Can you post the contents of the panic (and if possible, the backtrace)? Hi! Here's the coredump: espcoredump.py v0.3-dev INFO:Read TCB 356 bytes @ 0x3ffbb9b4 INFO:Read stack 1148 bytes @ 0x3ffbb530 INFO:Stack start_end: 0x3ffbb530 @ 0x3ffbb9ac INFO:Read TCB 356 bytes @ 0x3ffbc88c INFO:Read stack 4...

Hey everyone, I have a multi_master spi going. When the one master takes a long time to communicate with the esp32 the device panicks. Essentially the spi_slave transmission call is done with the following: ret=spi_slave_transmit(HSPI_HOST, &t, portMAX_DELAY); I know that it is this causing this as ...
