Esp32 IOMUX GPIO ADC REMAP

Hi,

We are checking if it is possible to remap the ADC port from a pad to another gpio non ADC pad?

Like GPIO36, ADC1_CH0, RTC_GPIO0 from PAD 4 to another GPIO IO 3 PAD 34.

Please advise.

Re: Change Partition Subtype during runtime

We managed to successfuly update our partition table on deployed devices. The end goal was to remove the default factory partition to allow us to increase the size of the OTA partitions as our application is nearing the 1MB limit. This was facilitated by our application and supporting infrastructur...

Re: ESP32: Partition Table Update through OTA

Hello, I just wanted to share my findings about this topic of updating partition table through OTA, for future users who fight this. I faced this problem because we wanted to change partition table from FACTORY+OTA to OTA0+OTA1, plus we wanted to expand NVS partition size. We got several devices al...

Re: High Level Interrupt on external GPIO Interrupt

Before the two last lines that return from the interrupt, can you try adding this? l32r a14, .GPIO_STATUS_REG l32i a14, a14, 0 memw The idea is that the interrupt acknowledge may be 'stuck' in a load/store unit of the CPU or somewhere in a peripheral, and hasn't properly executed yet before the int...

How Invert a GPIO port state ?

Hi,

In an output gpio that was set to a high state, how can I read later if it is High or Low?

Reading the code of gpio_get_level do not work on output, so, how we can now if a gpio output is in high or low state?
