I have a combination bootloader application but I'm having trouble debugging the image in the upper section. There seems to be some issue with my firmware copying/flash writing code but it only happens when the upper image is running and writing to the lower image location (the first firmware copy to the upper location works fine). I don't know how to debug the upper image. I can trick the bootloader into booting the upper image but the debug symbols don't seem to align to the correct code if I do this.

Hello forum members,

i am looking for a way to encrypt an char array before those data are exposed via Bluetooth.

Those encrypted data later will be processed in a secure harbor. So transporting of those are

fully transparent and no security issue so far. What is the best economic way to achieve the

encryption? Maybe an public key based encryption is sufficient?

Thank you for taking time to read this and helping me out to find a solution.

I have been trying to run an application CE95272 on my CYCKIT-043 that uses SAR ADC and interrupts on a limit detection.  I saw one discussion on this same subject but there was never an answer as to why it was not operating. Could i get some help in using this type of approach in a similar design i am trying to do.  I am only wanting to measure current in a sense resistor and voltage on my power buss.  I will attach my project (CE95272) for review.

For me i never see an accurate measurement ... say i put in 20mV i should see 200mV on Uart to PC Screen.  This never happens it either runs continuously reading and displaying the wrong values.

I am designing a new controller with touch keypad..Since its for an industrial application I would like to know the various failure modes associated with Capacitive touch keypads.

Hello,

I would like to confirm the rules for Opamp and ADC connection.

when OpAmp is used for signal amplification.

- The gain is determined by the external resistance of R1 and R2.

- The output of the OpAmp is output to the external pin via the 10x buffer.

- The output of the OpAmp and the input of the ADC have to connected not via the internal wiring but via the external analog pin.

Please review attached pptx file.

Hello, I'd like to write an LCD 2x16 (I'm working with LCD Keypad Shield, picture attached). It seems that LCD_Position() is not working.. when I print a string I just see the last character on first position (fw attached). Do you know what is the problem or an example with Psoc4 BLE + LCD?

Thank you.

I used this function a lot throughout code.

Every second.

Before entering Sleep.

After CyBle_GappSetNumOfAdvPkts().

I noticed that my sleep function on advertise tends to be interrupted less when i masked some of the calls to CyBle_ProcessEvents().

Is there a correlation?

Hi, i get a very large number of e000 ble interupts (CYBLE_DEBUG_EVT_BLESS_INT) , larger than advertising amount.

i have stopped Advertising by using : CyBle_GappStopAdvertisement();

in a loop, every 3 seconds i send a constant amount of packets by using : CyBle_GappSetNumOfAdvPkts(&cyBle_discoveryModeInfo, 3 packets);

but instead of seeing 3 interrupts every 3 seconds , i see 3 interrupts every single second.

Hello,

The provision of the Internal Vref Startup Time of the component data sheet

Is it only the standby time at PowerOn? Or is it necessary to wait for every AD conversion?
