have you found?

Suggest you read the technical reference manual (in as far as you haven't already) to handle interrupts on the UART side, but to connect the interrupt to an ISR, it'd be best to use esp_intr_alloc . You can do it by poking directly into the relevant registers as well, but since the ESP32 does run ...

Hello, can someone explain to me how to change the CPU clock? I tried the following
I don't know what to do at the moment... >


const uint8_t cpu_clock_source[][3] = {
//SYSTEM_SOC_CLK_SEL | SYSTEM_PLL_FREQ_SEL | SYSTEM_PERIOD_SEL
{ 0 , 0 , 0 },
{ 1 , 1 , 0 },
{ 1 , 1 , 1 },
{ 1 , 0 , 0 },
{ 1 ...

i only read this register..

hello @all,

i try to change the cpu clock source (by manipulating registers) and read the
( SYSTEM_SYSCLK_CONF_REG & SYSTEM_CLK_XTAL_FREQ_bm ) xtal frequency, i become everytime 40mhz.
it will be not change -.-*

i try to change like this ->


void app_main(void)
{
sys_set_cpu_clock_frequency ...

i allready have try this, have you seen my picture in #1?
there you can see short spikes.. i dont no why^^

I dont use the framework.
I want to now how I can do this with Register…

good evenig,

i use a c3 in spi master mode.
which register must be write to handle the cs pin by my self?
i have try to disable the mapping for FSPICS0 but i become a cs from about 40ns (see picture)

thx

I have another question about the SPI interface in single transfer mode.

You can fill the registers from SPI_W0_REG - SPI_W15_REG with data.

When I call my function, it sends the contents of SPI_W0_REG, but SPI_W1_REG is also filled with data.

How does it work that it also sends the second ...

The number of bytes is correct. Is it possible that there is still a bit that needs to be queried if the transmission is ready?
