Good afternoon I've had OTA working in the past so now I'm stumped as to why it's not working. So, I used the IDF example "native_ota_example" code to go back to basics, which gives the same result as my project code. Environment is Eclipse with ESP-IDF 4.3.3 ... and I've just ascertained that with ...

Fixed, thank you.

Good morning
I have OTA (Over the Air Updates) working well in my project and I use "version.txt" to control the updates to the software. My question, is there a variable that accesses the text in the "version.txt" file that is accessible to the code?

Thanks in Advance

Hello group A happy New year to one and all. My question. We have a program based on the ESP-IDF "http - rest_server" working well, but it is far too slow in loading. A mechanism we used with Arduino was to tell the browser to use its cache contents, having established a high cache age. This can hel...

Next problem.... I'm using esp-idf v4.4 and It seems the limitation of using DMA with SPI still exists... The master SPI only ever sends 5 bytes so I have DMA switched off, no problem, except 5 is not a multiple of 8. There is however one master command that expects to receive 1280 bits, which is no...

Evening
I liked your last reply, but I didn't spend too much time on it as "it didn't work". Maybe because the code wants to tell an "input pin" to modify it's level, which isn't done.
So, I've used 2 pins to get past this problem and I'm advancing again with the next 1000 lines of code
Many thanks

Hello again trying to make a single ESP run what I need, I assume I need to unite "a GPIO pin" with the "spics_in" signal of the SPI slave. Investigating I thought that this would do it ... esp_rom_gpio_connect_in_signal( someGPIOpin, spi_periph_signal[SPI3_HOST].spics_in , false ); However a high/l...

Good news thank you. it was what I needed to unblock this problem. I moved my test code to esp-idf to have more control on the SPI's and took control of the incoming CS line to the SPI slave on the ESP, having modified the CS line logic on my "black box". The annoying pulse in the middle of trace-4 ...

Thank you again. I shall make another incursion into this possibility, probably tomorrow or so.

Thank your for your reply. I was wondering if there is a way to use interrupts on the CS line?
I have investigated the esp-idf code looking for possible solutions, but so far I haven't had any luck
