Re: ESP-IDF V4 on PlatformIO

OK - probably my mis-interpretation of the last post in https://community.platformio.org/t/how-to-use-esp-idf-current-version-from-https-github-com-espressif-esp-idf/4598/14 where they do actually say they don't integrate beta releases (my emphasis of the work I managed to skip over). I'll take this...

ESP-IDF V4 on PlatformIO

Now that ESP-IDF V4.0 has been released (and thank you for that), is there any word on when a version will be released that can be used on PlatformIO? I've written code that needs some of the new V4 BLE API but when I have tried to copy the previous V4 development versions to PlatformIO, I've ended ...

Re: SPI Master Slave handshake with spi_device_queue_trans

I might be wrong here but I suspect you are thinking the SPI module operates in the same was as the UART. In a UART you can have separate send and receive operations - they can even overlap (i.e. send while receiving). With the SPI module, you *exchange* values - the master controls when the exchang...

Re: Synchronizing SPIs

Got it now - you are talking about Quad SPI (QSPI)

Re: Synchronizing SPIs

Now I am more confused. SPI is a serial exchange protocol which means that each bit of a value being sent is presented to the MOSI (for a master - MISO for a slave device) pin in line with the SCK transitions. Therefore I have no idea how this relates to the gpio_matrix_out function. You don't menti...

Re: Synchronizing SPIs

I suspect this is an 'X-Y' problem; therefore what are you trying to do that requires synchronised SPI exchanges? You *might* be able to do something like: - make one SPI module the master and all others slaves - the master will generate the SCK signal and all others will use that - because SPI is a...

Re: Need to enable and disable all interrupts

Don't be too hard on the OP. Stopping interrupts is a common way to make a series of non-atomic operations 'atomic'. For example (not necessarily from the ESP32 world) - reading a 32-bit value from 2 16-bit registers. In some cases the hardware will expect this and copy the top 16-bits to a special ...

Re: Python requrements --- esp-windows-curses and sys_platform == 'win32'

The issue I've had with PlatformIO is that the SDK is V3 whereas the functions I wanted to use (in the BLE area) were all in V4. Looking at the Platform IO forums, they all seem to be waiting for someone in the ESP32 world to port the V4 SDK over to them. (Note that this experience was a month or so...

Re: Turn off wifi and bt?

It might be my ignorance or my misunderstanding your question, but I thought you had to turn on both BT and WiFi.
Therefore neither should be working if you have not called the functions to turn them on.
