Re: ESP32 16MB Flash on VSPI

I had to drop to DIO with external flash too with similar errors. I used the same lines as the WROOM's flash except CS, and set the fuses. Dual layer board. Plan is if I want 16MB flash to use the new WROOM modules with 16MB flash, so have not gone further yet. Have had a layout with external PSRAM ...

Re: My long path to configuring the RMT and PCNT to share GPIO

I read a continuous pulse train so never get a receive interrupt. So I use a 10ms task to process the RMT buffer, which works OK for my frequency.

Re: APSTA mode, IP addresses, Android reconnection

On two laptops, Intel Centrino N6235 and N2230 are the problems. Changing to an old Broadcom WiFi adapter and all is well. Changing back to N6235 on one laptop breaks it again. In ATPSTA mode with Intel Centrino WiFi only, the ESP32 reports a station has joined, but the station reports the password ...

Re: APSTA mode, IP addresses, Android reconnection

The issue seems specific to Intel Centrino N 6235 devices I have in two PCs. Despite reinstalling the latest Intel drivers. I will see if I can change the wireless card in one laptop to prove it.

Re: APSTA mode, IP addresses, Android reconnection

Here is the WiFi code I'm using. In this form, I can see in the serial output from the ESP32 that it has STA_CONNECTED, got an IP address I can ping. It also has AP_STACONNECTED but if using WPA2_PSK, Windows says the network security key isn't correct and WiFi icon flashes, if using no security, it...

Re: APSTA mode, IP addresses, Android reconnection

Thanks, the second part is Android specific, and I am looking through that link, thanks. APSTA mode gave problems on Windows too where the networks were found but most of the time Windows would not connect to the AP (WiFi icon flashing, complaints of incorrect password) and the STA did not transfer ...

APSTA - works with Broadcom but not Intel Centrino WiFi [title changed]

Read all the docs and previous posts on this. I enabled APSTA mode but could not consistently get a connection like I can in either AP or STA mode despite good signal strength. I wonder if it is something to do with IP addresses and wondered if there is a working example to investigate more so that ...

I am not using Eclipse or Linux but the above might help? A colleague just loves subdirectories :)

Re: Can ADC read be interrupted?

From a single 1M CAN bus I cannot work out how you could get 4 frames in 42us?
