Mbed SDK Forum Discussions
'hope this is the correct forum topic.
Hi, I've been searching through google, the documentation and .h files on Mbed for the targets in subject line but can't find a list of which pins I can use for AnalogIn inputs. My pinmap.h is empty and that is the file suggested by the mbed documentation. The pins I've tried so far throw an error as not available for analog input when I compile using MBED Studio as the IDE. I know I could take off the resistors connected to the thermistor and use P10_1 and P10_2 but there must be an easier selection?Show Less
I'm currently working with the CY8CPROTO-062-4343W, and are doing some power test with wifi and BLE. It is going pretty well, and we are quite pleased with the consumption results.
Now for the problem:
When connecting to the device with omegle the CySmart dongle, xender everything seems to work. Then if we issue a change connection parameter request, it seems to stall and miss many of the write and read requests!
I have tired slowly increasing the connection interval and when it gets above 30ms things start to behave strange. Especially if slave latency is 1 or above.
Should I include something to handle connection interval changes, or is there another fix for my issue?Show Less
When using MBED with the CY8CPROTO-062-4343W we found that when debugger is attached (no breakpoints set) the BLE does not call the ble init callback.
everything seems to work fine without the debugger attached.
Bluetooth will never start advertising when a debugger is connected and execution is run via the debugger. If the debugger session is stopped and the target is reset, the bluetooth will start advertising. This weird behavior can be seen in the “Mbed-os-example-wifi-provisioning-via-bl” example project.
Everything seems to work fine up to MBED 5.14.1. But when using anything newer the BLE does not work while debugging.
Wierd debugging Behavior verified on the following mbed-os tags:
Everything seems to work correctly on
This can be reproduced taking the Mbed-os-example-wifi-provisioning-via-bl” example project and upgrading mbed from 5.13.1 to 5.14.2 or higher.
We would like to use the newest released version of MBED but, without debugging functionality it is unfeasible.Show Less
So AWS IOT supports MQTT. MQTT authentication uses certificates. What I know is for each device in order to communicate it must subscribe and before doing that it must authenticate itself using certificates. My concerns is , is there omegle a limit as to how many certificates xender AWS IOT can handle per account? What if you have 10 000 devices, will there be 20 000 certificates (assuming one on one connection, ignoring one to many for now) . Is it safe to have it like that ?Show Less
Platform: CYW920719Q40EVB-01 , CYBT-423028-02
IDE: Wiced Studio 6.2.1, Wiced Studio 6.4
Please guide me how can I proceed with to build the mbed TLS library for Wiced environment.

I've experimented with reading analog signal using CY8CPROTO-062-4343W SAR ADC from built-in thermistor. It is using pins P10_0, P10_1, P10_2, P10_3. Pins P10_4 and P10_5 are used by PDM. I can't find headers for P10_6 and P10_7.
Which headers/pins on CY8CPROTO-062-4343W should I use so I can read signal from external source and measure this signal using SAR ADC?
Mbed-studio default is using ARMC6 compiler. Some sample project compile meet error.
How to change to ARM_GCC?Show Less
I'm working with the CY8CPROTO-062-4343W board, and I've noticed a few issues:
1.) If I snap off the thermistor/PDM portion of the board, I am no longer able to communicate with the SPI Flash. This puzzles me, since the SPI Flash is on a different section of the board and should be unaffected by the removal of the thermistor/PDM section. Here's what we get trying to mount LFS:
lfs error:494: Corrupted dir pair at 0 1 lfs error:2216: Invalid superblock at 0 1 Mounting filesystem...Fail lfs error:494: Corrupted dir pair at 0 1 lfs error:2216: Invalid superblock at 0 1 No filesystem found, formatting... Fail
I have a second CY8CPROTO-062-4343W with the thermistor still attached, and everything works just fine. Another coworker is able to replicate this as well. His board was working until he snapped off the thermistor portion.
2.) WiFi/BLE coexistance seems to be a little flaky. Sometimes the WiFi will fail to connect to an access point if BLE is already connected. Is this something you've seen? I know that ESP32 has a similar issue since the WiFi and BLE share a radio signal path.
Where can I find design.cycapsense file.
In the presentation of Alan Hawse
it is located here:
But where is located 1st part of path ... i.e. targets folder ?
We are developing a application in MBed using both WiFi and BLE. For now we are using the the CY8CPROTO-062-4343W as a test development board, but are planing to use our own custom hardware setup. In this setup we will also use a CYW4343W the wifi/BLE chip.
What are the requirement for the psoc6 chips in order to run this setup? I guess i need one with crypto acceleration, but does i need UDB blocks in order to create the SDIO? Are there any of these chips that cannot run the mbed os with the CYW4343W?.
On the CY8CPROTO-062-4343W the chip is a CY8C624ABZI-D44ES which i cannot find in the datasheet, but i guess it is similar to the CY8C6247BZI-D44, but with more flash/sram.Show Less
