Re: PSRAM cache - how/when to update toolchain?
Thanks, I'd really like to install the updated toolchain on windows, but I cannot work out how to do it. I can manage to add the volatiles and change the binaries in newlib. I can extract xtensa-esp32-elf-win32-1.22.0-98-g4638c4f-5.2.0-20190827.tar but the contents are smaller than the original tool...

Re: RMT - simplest receive example working, but idle_threshold problem
Inside a task on a loop: while (item->val==-1) { if (RMT.status_ch[rmt_rx.channel]==0x04000000){ //overflow action } } Receiving the buffer contents: for(i = 0; i < (uint8_t)RMT.status_ch[rmt_rx.channel]; i++) { lowus = !(item+i)->level0*(item+i)->duration0 + !(item+i)->level1*(item+i)->duration1; h...

Re: RMT - simplest receive example working, but idle_threshold problem
Init, sorry the tabs don't display correctly. BUFS and INPUT need to be defined. rmt_config_t rmt_rx = { .channel = 0, .gpio_num = INPUT, .clk_div = 80, //1MHz .mem_block_num = BUFS, .rmt_mode = RMT_MODE_RX, .rx_config = {.filter_en = true, .filter_ticks_thresh = 255, .idle_threshold = 30000} }; rmt...

Re: Wear levelling FATFS performance really slow even for reading?
I abandoned FATFS for reading large files and only write small difference files to it. Large files are stored in flash at OTA update time and read using mmap.

PSRAM cache - how/when to update toolchain?
https://github.com/espressif/esp-idf/issues/2892 Thought I might be better asking here my question about when/how to update the toolchain on Windows as it might be too basic for the GitHub issue. Any advice appreciated, was waiting for ESP IDF 3.3 to release our product, but I am confused what to do...

Re: ESP-IDF v3.3 LTS clarification
On 5th September just after it was announced I updated and see this: $ git status On branch release/v3.3 Your branch is up to date with 'origin/release/v3.3'. The binary from the build shows: 13:39:25 Sep 5 2019 v3.3-rc-24-g148a26980 Is the -rc just an old tag? I did not notice this until I asked fo...

Re: RMT - simplest receive example working, but idle_threshold problem
Yes by having a task empty the buffer. RMT doesn't work with continuous pulse trains otherwise that I could work out.
