hi

Using the free run ADC sequential read, but occasionally get the reading 0xFFFF.

using this flow in a loop :

ADC_SAR_Seq_1_StartConvert();

result = ADC_SAR_Seq_1_GetResult16(CHANNEL_0); -> here i read 0xFFFF

cypress_result_mVolts  = ADC_SAR_Seq_1_CountsTo_mVolts(CHANNEL_0, result); -> here i get some abnormal value as well.

ADC_SAR_Seq_1_StopConvert(); -> using this to save some power.

the 0xFFFF read,

Can i assume this is zero? or is it some kind of glitch?

I don't think that a negative current can occur in my system.

hello, here I attached my project, im using mpu6050 sensor to run 2 motors. I should control the speed and the direction of the motors but Im struggling with writing the loop and getting the values for the gyroscope and the acceleration. I really need helps with that so please check the file that I attached. Thank you.

Hi,

I am attempting to install PSOC Creator 4.2 from the Cypress Website, however, the installer stops responding as soon as the License Agreement windows displays. I am running Windows 10. Please help!

I am installing from the link below:

We have an application where we need to control several ble devices at the same time. Was looking at the "Time Multiplexed" example in 100 proj/days but found that there's at least a 100ms delay to swap to the next device. We need to be able to update the peripherals faster than that, is there any way to reduce that delay down to 20ms or so?

dear FAE, i have a question for design a 8bit division on psoc4, my design is use a counter to count event from the psoc4's pin, and later use DMA to transmit the data to a DAC, but between the counter and DAC, i want to use 0xFF/data, and the quotients transmit to DAC, but i can't find the model which can use on this design, so if you have a good method, the can send it to my email which is keeny.zhao@163.com, i'm in China, thank you for you help.

Hello,

I'm adding the fixed stack bootloader to my application which worked fine so I could build and flash the new project. I'm using the CYBELE-212006-01.

I can connect to it but when I select the Bootloader Service the CySmart application gets stuck while trying to bond. The device apears 3 time with different adress inthe serch but two of them don't even have teh Bootloader Service.

Where could I have gone wrong?

Hi,

I'm trying to send 20 bytes via notification from CYBLE-012011-00  module using an " uart to ble peripheral" project to cySmart app but the 20 bytes ar splitted in two parts (12 bytes and 8 bytes ).

For Example my 20 bytes are : 03 06 00 00 00 00 0f 91 90 00 00 80 00 00 00 00 00 00 00 00

On the Data Logger file.txt I find

...Notification received with value, [03 06 00 00 00 00 0f 91 90 00 00 80]   4 times

and

...Notification received with value, [00 00 00 00 00 00 00 00]   4 times.

Why the Notification is splitted and repeated for 4 and 4 times?

Many thanks

Here is the original thread that addresses this issue.  I2c Issues

The issue is marked as answered, but there is no answer to the original question:

Are there known issues using P5.0 and P5.1 as allowed by PSOC creator on this module?  I am not getting an ACK if these pins are used.

If I assign the pins to P3.4 and P3.5 (allowed for SCB1 sda and scl), I get proper ACK and function.

If someone could help, I would greatly appreciate it.  I already have a board layout done using P5.0 and P5.1.
