Re: Large web server on WROVER

Cool, Thanks. I will sack that team member & destroy his family ;)
Awesume to have the B series; I can get 16Mb flash! The finance ppl will just have to suck it in.

Guess that we have the same cache restriction on Flash write and RAM access. Hope that's on the plan :)

Re: ESP32 CAN

I have used the ESP32 CAN. We are early in the design but I have clocked up >10 days stress testing back to back with an MCP2515 before moving on to other things. Only used two of our prototypes and an ESP32-EVB so far. PS @ Snipesy There is a driver but it has not yet been included in ESP IDF produ...

Re: Large web server on WROVER

Thanks, yea we spotted this but think that its a Mouser mistake. The pricing is the same as the 4MB version and the linked datasheet says that its 4MB, 8MB. I understand that datasheets may lag especially when just a memory option but the pricing....

Large web server on WROVER

Hi, I need to host a large web site (3.3MB+ minified) on a WROVER. The ideal would be to use SPIFFS but the WROVER's 4MB flash is too small. I also read that the spi_flash library is only suitable for use with the 'main' program flash (SPI0). We will fit something like a W25Q128JVSIQ to our board. T...

Core dump using putty

Hi, This must have been answered before but I cannot find the answer. My program hangs and I want to capture trace and core dump information. The PC is connected to the ESP32 via our board's CP2102N UART to USB. The CP2102 RTS and DTR are connected to ESP_EN and GPIO0. When I open a session our boar...

Which is a FreeRTOS task handle? That is to ask if I could use that handle directly to change priority etc?

C++11 threads

I have a third party library I would like to include into an my ESP-IDF project. The library uses C++ threads, mutex etc. My FreeRTOS task would call a library function. The library function would block on a C++11 mutex before sending to a C++ queue. A C++ thread would use the mutex to gain the queu...
