Resolved! STM32WB55CGUX (48 pins versions) microcontroller with Touch Sense Controller (TSC) capabilities

Hi,we are looking for a microcontroller fitting the following features:1MB Flash256kB RAM BLE48 pins (non BGA)Touch Sense Controller (TSC)Active and stockWe pointed to STM32WB55CGUX but we see the following note on the datasheet STM32WB55C (page 48):...

Resolved! What does TSC_IOASCR do?

What does the TSC_IOASCR register do?Checked the reference manuals for STM32 WB35xx/WB55xx (RM0434) and F0xx (RM0091) and only get the following information: What's the behaviour of this setting for pins in the various modes (unused, sampling, channe...

Resolved! In touch sensing controller feature, can i adjust the threshold voltage in reference capacitor (VIH where the count value taken to charge the reference capacitor to this threshold value). IF the reference voltage can control how can we do that?

Resolved! IN STM32WB55 touch sensing features, at which range of capacitance value touch sensor can be used? It say few picofarad, do any exact capacitance range for proper working? if i use a dedicated touch sensor with 100pf nominal value do it will work?

Can the TSC be configured to support more than one active shield?

Our application has two touch sensors surrounded by a shield and an additional independent sensor surrounded by a separate shield. The first pair of sensors are connected to TSC groups 1 and 3. The other sensor uses groups 4 and 6. Groups 1 and 4 con...

Touch Sensing Controller - Rising/Falling edge detection on CapTouch Button

I am using a STM32WB55xx controller for my project. I am trying to implement the capacitive touch behavior to detect button press on rising edge and button release on falling edge (please see document attached for details)Q1. Will the Touch Sensing C...

STM32WB55 TSC is not working

In Group 1 G1_IO4 is a sampling capacitor and G1_IO3 is a sheild and in Group 2 G2_IO2 is sampling capacitor and G2_IO1 is input touch key. In Group 3 G3_IO4 is a sampling capacitor and G3_IO2 is a input touch key. so when i programmed with this conf...

About TSC function of STM32WB55CGU6

Hello there! I am debugging the TSC function of the STM32WB55CGU6. I cannot set the TSC function in MubeMX. However, in the official materials, I learned that the TSC function can be supported through the txt file. Refer to the STM32L476G_EVAL board ...

Resolved! Unable to understand TSC connections in STM32WB

Hi Sir/Madam,The Sensor Capacitor (Cx) is not connected in the below mentioned. Can you please provide clarity on the Cx connection with MCU.While configuring the shielding in TSC using STM32CubeMX, it is asking to configure Cs(Sampling Capacitor) in...
