PSoC™ 4 Forum Discussions

Hi everyone,

I am new to this group, I need a help for programming  CY8C4245axi-483.

Can I use CY8CKIT-049-42xx PSoC 4

For programming the external CY8C4245axi-483. If it is not useful. Please suggest me the suitable programmer.

Thank you in advance.

Hi,

I am testing the component Die temperature with the boad CY8CKIT-041-41XX, bur the temperature value is wrong: -30°C at 25°C ambient.

I am using your example code called CE195275 – Sequencing SAR ADC and Die
Temperature Sensor with PSoC 4.

Why is there this difference ?

Best regards

Hello Team Cypress,

I am here to ask for a Cypress MCU in order to replace  Microchip's ATSAMHA1E15A-B(32-pin QFN)
https://www.microchip.com/en-us/product/ATSAMHA1E15A-B 

The MCU part, that we seek, shall
-have the automotive quality.
- be used for the step motor starter application for "active grille shutters" 
- be used along with the LIN step motor gate driver from Infineon (see the blocks above).
- support LIN+SPI communication protocol (the MCU will run in LIN slave mode)
- have an equal or smaller packaging size with the products listed above preferably due to PCB size.
- have a relatively good delivery date in terms of logistics.   

If you could suggest
specific model with the part number
from the Cypress automotive quality MCU
for the MCU part of the design block,
that would be really appreciated.

Thank you in advance. 

Sincerely,
Ben

My team and I are looking for a suitable Cypress Automotive MCU part for the following applications and features needed.

One of my clients is considering to replace a MLX81315 Melexis with a Cypress MCU part.
Smart LIN driver IC for DC, stepper, BLDC motors (MLX81310/15) #Melexis

There are available candidates listed on the left side block of the diagram above,
but I am here to ask for advice if there is any automotive quality Cypress MCU part suggestion adequate for the job.

The MCU part, that we seek, shall
-have the automotive quality.
- be used for the step motor starter application for "active grille shutters" (which help the vehicle's aerodynamic design).
- be used along with the LIN step motor gate driver from Infineon (see the blocks above).
- support LIN+SPI communication protocol
- have an equal or smaller packaging size with the products listed above preferably due to PCB size.
(S9S08SL8F1MTJ (TSSOP-20) /  ATSAMHA1E15A-B(32-pin QFN) )
- have a relatively good delivery date in terms of logistics.   

If you could suggest us the Cypress automotive part that fits the MCU part of the block, that would be really appreciated.
Thank you in advance.

Hello,

The Arch TRM explains the following in "9. Clocking System".

- 24–48 MHz internal main oscillator (IMO) with ±2 percent accuracy across all frequencies with trim

- 40-kHz internal low-speed oscillator (ILO) with ±60 percent accuracy with trim

Does the user need to process something for ILO trim?

For IMO trim, I understand that the flow in "Figure 9-2. Change IMO Frequency" is processed in PSoC Creator generated source before entering the main function.

Best regards

I am trying to connect to a PSOC4 BLE device via PC using Cypress DLL. 

When I try to pair to the device, the DLL function (result.Device.Pair) returns a "fake"  success,  because the device does not show  that pairing did succeed at that moment.

Questions:

1. Is there a way to know if pairing truly succeeded? Checking device side  is not an option.

2. If not, how long does "result.Device.Pair(cyPairSettings)" take?

3. This is another issue, why does sometimes GattMtuExchanged (..) does not occur? 
(after running :Peripheral_.GattClient.ExchangeMtu(cyGattExchangeMtuInfo);)

Thanks!

Dear Sirs and Madams,

I have a question about the description of the function in device datasheet.

PSoC4200M Datasheet URL

https://www.cypress.com/file/377971/download

For the tables on pages 12 and 13 of the datasheet,

It is described as "tcpwm.line[0]:1" or "scb[0].spi_mosi:1".

I understand that the numbers in "[]" are individual peripheral numbers.

What is the difference between "tcpwm.line [0]: 1" and "tcpwm.line [0]: 0"?

For example, P2[4] is "tcpwm.line [0]: 1", P3[0] is "tcpwm.line [0]: 0",

I thought that I could only assign one "tcpwm.line [0]" and one "tcpwm.line_comp [0]" in one TCPWM [0].

However, it uses two TCPWM components and both can be placed at "tcpwm.line [0]" in TCPWM [0].

I thought that if I assigned one "tcpwm.line [0]", I couldn't assign the other "tcpwm.line [0]".

Is it okay to understand in the sense that the above configuration is possible?

Please tell us the difference between "tcpwm.line [0]: 1" and "tcpwm.line [0]: 0".

Regards,

hello,

I set the pin P0.7 of CY8C4245AXI-483 to high. but it turns to high 1s after power-on.Power supply and reset are completed within 3ms.So what is the cause of this one-second delay?

As per the CY8CKIT-048 product page, latest PSOC could not be used to develop firmware for this kit to evaluate PSOC Analog Coprocessor. If that is the case, how the firmware development for PSOC Analog Coprocessor can be done using hardware development kit? I would like to evaluate PSOC Analog Coprocessor as a front end for STM32 based device.

Hi,

I am using theADC in single mode, but I noticed that is avaible the conversion in unsigned mode, why ?

All ADCs have the unsigned conversion.
