Hello,

I am trying to use two I2S instances to design a project for collecting data using im69d130 microphone shield2go from Infineon. As per the datasheet, I can use two I2S block. One is on port5 and other on port 11.

However, to startwith, I am trying to initialise I2S but initialisation fails. I am making use of HAL library.

Should I configure clocks for Shield2Go board, it has three pins: DATA, SCLK,WCLK? Is I2S instance master or slave?

How in general we can read mic data using m69d130 microphone shield2go.

My code looks like this:

1) cyhal_i2s_t i2s_0;
const cyhal_i2s_pins_t i2s_0_rx_pins = { .sck = P5_4, .ws = P5_5, .data =
P5_6 };
const cyhal_i2s_config_t i2s_0_config = { .is_tx_slave = false,
.is_rx_slave = true, .mclk_hz = 0, .channel_length = 16,
.word_length = 16, .sample_rate_hz = 24000u };
cy_rslt_t result = cyhal_i2s_init(&i2s_0, NULL, &i2s_0_rx_pins,
NC, &i2s_0_config, NULL);

 The result variable is expected to return 0 if everything goes well. It return me a big integer number that means I2S was not initialised. Can you tell me how to proceed?

2 ) Also, is there a way to see the value of variable with out optimisation? While debugging, I see <optismized value>.

I tried to use volatile keyword like volatile cy_rslt_t result , but I dont want to use it all the time. Is there away to turn off optimisation in debug mode? updating CXXXFlags in project make file does not work. 

I used emptyPSoC app to create the project.

Thankyou.

Hello....

Starting with Cypress controller, what development kit or code examples helps me to develop small test application to verify the proper working of UART, SPI, I2C, GPIO, Clocks etc. peripherals.??

I have IAR 8.4 Workbench IDE for programming and debugging code, so looking for example codes in IAR IDE support.

Hello,

I was approached by someone who required to use the PC's BLE instead of Uart serial to output PSoC logs and data. And since there was no sample, I made one.

The environment used is as follows:

・PSoC Creator 4.2

・CY8CKIT-062-BLE

In the case of Bluetooth, we were able to use SPP to represent it, but BLE does not have this profile, so we need to create a custom one. The communication between the PSoC6 kits was created by Yugandhar, so I used this Peripheral side program as a base and combined it with a simple printf sample. When the SW2 on the kit is pressed, a message is counted up and displayed on PC’s DOS window.

The program using BLE on the PC side has been created in C#/VisualStudio2019 and can be used as a basic program for PC BLE. It runs on the DOS of the PC and can pair with BLE devices and read/write, but in this case, we have chosen to run read directly after pairing. The menu is not shown in the comment out, but you can select Read or Write as well.

After the PSoC side program is executed, the PC side program is executed on Dos. The procedure is:

• Scanning for BLE Devices
• Connect to the PSoC 6 BLE kit
• Press SW2 on the PSoC 6 BLE Kit and verify that the message on the DOS updates.

The PC I am using is Win10 with BLE4.2. The result is displayed as follows：

Known issue：

As mentioned above, the first column is missing for some reason. So I put a blank in the first column of the message, but I hope someone will fix this bug and post it.

Thanks,

Hello,

I have prepared a sample project for interrupt processing from GPIO pins of the same port group.

This is based on "7.8 Pin Interrupt" in AN86439.

GPIO interrupts are possible from P0.2 and P0.3. This method will result in an error when building if the port numbers are not consecutive. For example, it cannot be set to P0.2 and P0.4. Since the IRQ is the same in the same port group, the same interrupt handler is used. Therefore, for example, the handler contains a judgment as to whether or not a P0.3 interrupt occurred during interrupt processing by P0.2.

Unfortunately, Pin_P0_ClearInterrupt () clears the pending interrupt bit of all bits, so any interrupts from other pins between the following will be ignored. It is necessary to devise such as adding the pin input to the judgment.

     while((uint8)Pin_P0_INTSTAT != intstatus_flag)
    { ...}

        **If an interrupt on another pin occurs during this time, it will be ignored.**

    Pin_P0_ClearInterrupt();

[Method of operation]

- Connect two tact switches as shown below.

- When you press SW3, LED4 lights up for 1 second. And when you press SW4, LED5 lights up for 1 second.

  If you press one of the SWs and press the other SW while it is lit for 1 second, two SWs will be processed in one interrupt handler, and LED6 will be lit.

Best regards,

Hello,

is there any sample code (Arduino?) for the CY8C95xxx IO expander?

Thank you

Hello:

I am trying to add a custom service to the example code in CE217643 i.e. the BLE Temperature Measurement

with PSoC 6 MCU with BLE Connectivity, Health Thermometer Profile example application.

I have added a custom service to the ble GATT server via the schematic BLE block parameters tool.  

The custom service has only one custom characteristic, the default uint8 field with read prosperities set.

The custom descriptor had one field the uint8 default.

I was looking for where the event handler or callback was/is for the custom service so I could access the custom characteristic value.

Why in the generated code module cyble_custom.c function Cy_BLE_CUSTOM_EventHandler... is there no code for handling a CY_BLE_CUSTOM_SERVER that my example is?

How ? and where ? do I write the Cy_BLE_CUSTOM_EventHandler for a CY_BLE_CUSTOM_SERVER?

What events in the handler do I need to look for, and what is in them?

Thanks Brian
