Hi Team,
How to read a voltage from psoc and viceversa. so that i can able to see in any available host.
Please help me to provide the steps.

Hi ,
Kindly check the PSoC Code examples available in PSoC Creator. In PSoC Creator, Go to FIle -> Code example. Inside that check for CE195277(ADC and UART) example available .
Best Regards,
Vasanth

Hi,
The project with serial number 12 named Pioneer Board oscilloscope from the link below may help you. This code example is for PSoC 4.
https://www.element14.com/community/thread/23736/l/100-projects-in-100-days#Projects%20Released
If you are using PSoC 3/5 the following code example might help you.
Kindly update if you need more information after going through the above documentation.
Thanks
Ganesh

Hi Ganesh,
I am using CY8CKIT-050 PSOC 5LP. In this kit How to read a voltage from psoc and viceversa.
Please share a psoc project which will use USBUART style of project.

Hi,
Please note that the community is not a place where you can order any programs free.
But you are required to learn from the helps/suggestions of others.
IMHO, you are supposed to be provided enough information to handle USBFS-UART from previous discussions,
and you should be able to learn from the sample code about how to use ADC.
Having said above, here is my simple trial/sample with CY8CKIT-050.
I connected a POT to P3_0.

#include "project.h"
#include "stdio.h"
#define STR_LEN 32
#define USBFS_DEVICE (0u)

{
int16_t adc_raw_count ;
int16_t adc_mv ;
int ch = 0 ;
ADC_StartConvert() ;
ADC_IsEndConversion(ADC_WAIT_FOR_RESULT) ;
adc_raw_count = ADC_GetResult16(ch) ;
adc_mv = ADC_CountsTo_mVolts(adc_raw_count) ;
return(adc_mv) ;
}
int main(void)
{
uint16 count;
int16_t adc_mv ;
char str[STR_LEN+1] ;
CyGlobalIntEnable; /* Enable global interrupts. */
/* Start USBFS operation with 5-V operation. */
USBUART_Start(USBFS_DEVICE, USBUART_5V_OPERATION);
ADC_Start() ;
for(;;)
{
/* Host can send double SET_INTERFACE request. */
if (0u != USBUART_IsConfigurationChanged())
{
/* Initialize IN endpoints when device is configured. */
if (0u != USBUART_GetConfiguration())
{
/* Enumeration is done, enable OUT endpoint to receive data
* from host. */
USBUART_CDC_Init();
}
}
/* Service USB CDC when device is configured. */
if (0u != USBUART_GetConfiguration())
{
adc_mv = measure() ;
if (adc_mv < 0) {
adc_mv = -adc_mv ;
snprintf(str, STR_LEN, "-%d.%03dV\n\r", adc_mv/1000, adc_mv %1000) ;
} else {
snprintf(str, STR_LEN, "%d.%03dV\n\r", adc_mv/1000, adc_mv %1000) ;
}
count = strlen(str) ;
if (0u != count)
{
/* Wait until component is ready to send data to host. */
while (0u == USBUART_CDCIsReady())
{
}
USBUART_PutData((uint8_t *)str, count) ;
CyDelay(1000) ; /* interval for measurement */
}
