following code causes crashes and you comment out release and delete it stops but i cannot use your mcp320x_read or read voltage inside a for loop or called in another function

1 year ago plus in you example i had to remove " .isr_cpu_id = INTR_CPU_ID_AUTO," from spi config because in esp 5.1.1 its not there

1 year ago You're acquiring the bus before the while loop and then releasing it and freeing the driver on every interation of your loop.
Calling mcp320x_delete will delete the driver, freeing all internal resources, rendering it unusable and causing the assert failed: xQueueSemaphoreTake IDF\components\freertos\queue.c:1545 (( pxQueue )) error when calling mcp320x_release on the next iteration.
Trying to free the bus (mcp320x_release) after it was freed will raise an error too.
Try this:
void app_main() {
spi_bus_config_t bus_cfg = {.mosi_io_num = GPIO_NUM_23,
.miso_io_num = GPIO_NUM_19,
.sclk_io_num = GPIO_NUM_18,

.data6_io_num = -1,
.data7_io_num = -1,
.max_transfer_sz = 3, // 24 bits.
.flags = SPICOMMON_BUSFLAG_MASTER,
.intr_flags = ESP_INTR_FLAG_LEVEL3};
mcp320x_config_t mcp320x_cfg = {.host = SPI3_HOST,
.device_model = MCP3208_MODEL,
.clock_speed_hz = 1 * 1000 * 1000, // 1 Mhz.
.reference_voltage = 3300, // 5V
.cs_io_num = GPIO_NUM_5};
// Bus initialization is up to the developer.
spi_bus_initialize(mcp320x_cfg.host, &bus_cfg, 0);
// Add the device to the SPI bus.
mcp320x_t *mcp320x_handle = mcp320x_install(&mcp320x_cfg);
uint16_t voltage = 0;
while (1) {
// Occupy the SPI bus for multiple transactions.
mcp320x_acquire(mcp320x_handle, portMAX_DELAY);
// Read voltage, sampling 1000 times.
mcp320x_read_voltage(mcp320x_handle, MCP320X_CHANNEL_0, MCP320X_READ_MODE_SINGLE, 1000, &voltage);
// Unoccupy the SPI bus.

1 year ago Your function calcIrms_with_mcp3208(int numberOfSamples, mcp320x_t *handle) expects a mcp320x_t pointer.
The following line might be the problem as you're passing the address of the pointer instead of the pointer.
irms = calcIrms_with_mcp3208(1048, &mcp320x_handle);Could you change it to the following line?
irms = calcIrms_with_mcp3208(1048, mcp320x_handle);for further debugging this the result of my core dump

Done!``Did you try the fix suggested on this comment?
I've changed the example and committed it.

1 year ago yes i have tried your suggestion of passing point instead of address still does not work your example does not in main_app()
there is some issue when libraries is called from other functions i will further test it out
Thank you for your help

1 year ago @isfandyarIOTMAV, you're deleting the driver on your calcIrms_with_mcp3208 function and you inverted the parameters on mcp320x_read.
I've adjusted your code, it is working now:
#include "esp32_driver_mcp320x/mcp320x.h"
#include "driver/gpio.h"
#include "driver/spi_master.h"
#include "esp_log.h"

#include "math.h"

double sqV, sumV, sqI, sumI, instP, sumP;
double realPower, apparentPower, powerFactor, Vrms, Irms;
double calcIrms_with_mcp3208(int numberOfSamples, mcp320x_t *handle)
{
uint16_t sampleI = 0;
double sumI = 0;
mcp320x_acquire(handle, portMAX_DELAY);
for (int n = 0; n < numberOfSamples; n++)
{
mcp320x_read(handle, MCP320X_CHANNEL_0, MCP320X_READ_MODE_SINGLE, 1000,
&sampleI);
offsetI = (offsetI + (sampleI - offsetI) / 1024);
filteredI = sampleI - offsetI;
// Root-mean-square method current
// 1) square current values
sqI = filteredI * filteredI;
// 2) sum
sumI += sqI;
vTaskDelay(10);
}
// Unoccupy the SPI bus.
mcp320x_release(handle);
double I_RATIO = 90.9 * ((3300 / 1000.0) / (4096));
Irms = I_RATIO * sqrt(sumI / numberOfSamples);
return Irms;
}

1 year ago thanks alot it is working I really appreciate your efforts
Cpu crashes when your example code is put in a while (1) loop with vtask delay
